Hiera configs and size detection from the weights, registry entries pinned to
commits with verified SHA-256, the loader picks the size by checksum. The GPU
encoder submits once per block so Large fits in memory, and uploads no longer

Sam2Mask wraps the image path behind the Roto Brush's MaskModel interface

load, use by Roto Brush 3.0, deselect.
